1、maven的pom配置，javassist和gson的jar依赖。
<!--GSON add by yxt 2020.10.15 -->
<dependency><groupId>com.google.code.gson</groupId><artifactId>gson</artifactId><version>2.6.2</version>
</dependency><!--javassist add by yxt 2020.10.15 -->
<dependency><groupId>org.javassist</groupId><artifactId>javassist</artifactId><version>3.20.0-GA</version>
</dependency>
2、java的aop配置代码：

import javassist.bytecode.LocalVariableAttribute;
import javassist.bytecode.MethodInfo;
import org.apache.commons.lang3.ArrayUtils;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
